FIRELESS-COOKER LINING.

Specification of Letters Patent.

Application filed March 22, 1909. Serial No. 484,888.

To all whom it may concern: 4

Be it known that I WALTER D. HoDsoN, a citizen of the United States, residing at Janesville, in the county of Rock and State of \Visconsin, have invented a certain new and useful Improvement in Fireless-Gooker Linings, of which the following is a specification.

-My'invention relates to linings particularly adapted to fireless cookers. I

It is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of the three compartment cooker with the lid raised; Fig. 2 is a cross section through a portion of such a device in its completed condition; Figs. 3, 4 and 5 illustrate the first three steps in connection with the lining of the case.

Like parts are illustrated by the same letter in allthe figures.

A A are the three compartments of the case B. This case contains the side walls C, C and the cross pieces D, D between its several compartments.

E is the lid.

F, F are strips fastened by screws or nails F to the top of the side portions of the case,

each projecting, as indicated at F G is the lining for the compartments which overlies the strip F and projects beyond the outward projection of this strip as indicated at G The projecting portions G and F are shown in dotted lines in Fig. 1 atone corner of thedevice. They are notched or cut away at the corner so as to permit the further process of folding them together and down. After the lining has been laid over the strip the outer part of its projecting part G is bent down underneath the projecting part F of the strip as indicated in Fig. 5. The two projecting portions are then bent down together as indicated in Fig. 2. The details of the structure are not shown in Fig. 1, simply the general outlines. This method of securing the lining of the case is pursued around the entire case and if it consists of but one compartment, then around the entire compartment. If, however, the case consists of a series of compartments then this method of securing is applied only to the outer portion of the lining. At the point where the lining overlies the cross strips D it is provided with a bent down edge II which is let into a groove in the upper part of such strip 1). Exactly the.

cess J is preferably formed about the edge of the cover and into it is let the strip F.

down the lining around the edge of the case and the cover. I also entirely cover this strip and the nails which hold it because the opening for access thereinto lies outside of the closed cooker or vessel.

I have described my device in connection with a fireless stove or heater, but of course it is equally applicable to any case or receptaclehaving a lid arranged in general as indicated in my drawings. I do not wish to be limited to the precise forms of construc tion shown, as of course a considerable va-- riation therefrom could be made without departing from the spirit of my invention. What I consider essential I shall set forth in my claims.

The use and operation of my invention are as follows: In fireless cookers the lids or the top of the cases are usually covered or lined on their opposed surfaces with sheet metal sections held in position by nails about their edges. This involves the expense'and trouble of driving a great many nails, it

tends to shatter and prepare for subsequent decay of the Wood portions of which such Patented July 16, 1912.

same method is proceeded with in reference 7 to the lining of the cover, though here a reheaters are commonly made, and it leaves the nail heads exposed to the moisture and the, acids incident to the use of such stoves, whereby the nails are rustednnd such linings or covers are speedily deprived of their securing supports. One of the objects of my invention is to dispense, as-farl as possible, with the useof these nails or to dispense with as many of them as may be possible and to secure a cover for the heads of such as are used.

I In the preferred form of my device a strip is let into the under side of the cover by slightly recessing about the edge thereof and nailing the strip into this position so that its outer side is flush with the general surface of the cover. In like manner a simi lar strip is nailed or otherwise secured on the upper edge of the sides of the case.

These strips extend beyond the outer edge position by crimping its outer edge over the edge of the strip and the whole is then secured in position by crimping or bending the sheet metal and the strip down upon the edge of the cover. In like manner the sheet metal within the case is placed in position, its edge bent over the" edge ofthe strip previously attached to the case, and the two projecting edges are then bentdown together against the side of the case. 'The strips in both of these cases can be puton with a few nails, thus obviating the use of so many as would be necessary according to the old method, though this is not ordinarily necessary. 7

In the modification shown I have suggested means for dispensing with nails and in some cases with the strips. The-sheet metal which I have here illustrated only in connection with the case proper iscarried down over the side of the case as before but it is then bent so as to be received into a recess along the side of the case. It is se-. cured in this recess by a strip nailed therein or a wedge forced thereinto: as shown in the drawings.

Accordin to 'my present experience I prefer the first form of device as above described.

I claim:

1. A receptacle comprising a case and cover each having a separate lining with outside edges, securing devices for such ;edges comprising a strip around the edge J ofthe cover and the case and projecting be yond the same, and nailed into position, the g projecting edges parallel with the edges of the lining and lying between the lining and the body of the case or cover, said strip and said lining interlocking.

3. A receptacle comprismg a case, a lining having outwardly projecting edges, a securing device for such edges comprising a strip rigidly attachedabout the edge of the case and projecting beyond the same, said strip lying beneath the outwardly projecting edges of the lining, said edges beingbent about the edges of the strip, and the lining and strip being bent downwardly parallel with the outside ofthe case.

4. A receptaclecomprising a case, a lining with outside edges, securing devices for such edges comprising a strip around the edge of and nailed to the case' and projecting beyond the same, a part of said strip being approximately perpendicular to the walls of said case and a part of said strip being at right angles to said perpendicular part and folded within the folded edge of the lining.

5. A receptacle comprising acase having a lining, the edges of which project outwardly beyond the wall of the case, holding strips, means for rigidly attaching said strips to the case, said means being covered by the edge of the lining, said strips and saidlining edges being bent one about the other and bent downwardly about the wall of the case.
